When you get the Egg, what is the number you are supposed to remember for?
There's no number that's needed to remember.
I for one, am having troubles with figuring out how to remove those dang ticks. Please tell me?
If you mean the injuries that require you to pull out a certain material then this is what you have to do.

You see the white line around the metal piece? What you have to do is really simple. I suggest to sedate your patient about 4 times before doing so. First, click (of course) and slowly move the metal piece OUT of the body. If you touch the border white line, the piece will go back. Second, pull it out as far as you can then the piece will disappear . That mean you took it out successfully.
